Tuning - Major Diatonic, Part 12 (F Blues Scale, Part 1)

Let's now look at the IV7 Chord in 1st Position

IV7 Chord
- F A C Eb

IV7 Chord Blues Scale
- F Ab Bb B C Eb F

First Octave: (1+) 2" 3''' 3' 3 4 5
This is fairly complete, but the flat-7th is missing and very challenging to play due to the tricky bends.

Second Octave: 5 6' 7 7+ 9
This is not very complete and awkward to play.

All said, this is doable, but tough... not many players know how to play a IV7 Chord in 1st Position well (me included!).
